All Budget Headers are NOT Created Equal!Hooker's Competition Series Headers come in your choice of finishes and are engineered to perform at a reasonable price! To let your engine really breathe, Hooker utilized 16 gauge (.049'' thick) steel tubing attached to long transition style collectors. Giving you a serious increase in flow over other brand headers without a loss in the backpressure most engines need to perform! After years of testing, Hooker has discovered that a machined 5/16'' header flange offers enough flex to hold the gasket tight to each exhaust port plus enough rigidity to keep everything properly tied together.

Features

Mandrel-bent tuned-length tubing for smooth exhaust flow and power

Sturdy 16 gauge steel tubing

Perfect seal 5/16'' machined header flanges

Long transition collector for improved power over standard headers

Gaskets and bolts included (Reducers sold separately)

Available in five finishes to suit your needs (see listings below for product availability) -

Good , but needs modification to fit 1969 Firebirdcenter ports would not allow a bolt to fit. had to heat up and beat with a hammer to allow more room. Decent overall , but no way a bolt or stud could ever fit as center pipes were at a real tight angle. very frustrating!!!...
